Abstract: PURPOSE:To improve the illuminance distribution of an image formed by two separator lenses and to prevent an erroneous decision at the time of detecting and deciding a focusing state by an extremely simple constitution by curing a pupil decision use diaphragm mask placed in front of a re-image forming lens so as to turn the concave surface to an object side. CONSTITUTION:A pupil division use diaphragm mask I placed in front of re- image forming lenses 5-A, 5-B is not formed to a plane but curved so as to turn the concave surface to an object side. In the case when a form of the curved diaphragm mask I is used, an edge of the diaphragm separated from an optical axis moves to the front of an original diaphragm position, and as a result, the diaphragm mask I becomes an inclined shape. Therefore, an incident angle of an incident luminous flux to the diaphragm mask surface becomes large. In this case, by selecting suitably thickness of the diaphragm mask I and a curvature of the curve of the mask surface, the light quantity distribution can be controlled. In such a way, a difference of the illuminance distribution can be made small, and a malfunction and an erroneous decision at the time of the focusing detection and decision can be obviated.
